Question

derivation for formula of force; f=ma. step by step explanation​

Answer 1

Answer:

Explanation:

If a body of mass "m" moving at initial velocity "u" accelerates uniformly with an acceleration "a" for time"t" so that it's final velocity changes Into "v".

then initial momentum p1 = mu

final momentum p2 = mv

change in momentum = p1-p2

= mv-mu

= m(v-u)

according to 2nd law of motion

F = change in momentum ÷ time

F = p2-p1 ÷ t

F = m(v-u)÷ t

F = ma 《 v- u ÷ t 》

hence derived...
